Any more details on Homekit?

Any more details on Homekit support? It’s been a few months now since WeiWei said HomeKit support was coming in 2018.

Working with Apple now and struggling with WiFi-certification and MFi certification. It’s not that easy to get MFi and it’s even harder to support dual stack.

Is Apple giving any idea on how long this process will take until users can access this feature?
